Abstract

La présente invention concerne un procédé et un dispositif qui permettent de fabriquer des toiles métalliques cylindriques extensibles (100) destinées à être utilisées dans des stents extensibles et plus particulièrement la fabrication sur mesure. Le procédé consiste à déterminer le type et la taille du stent à implanter, à former par processus électrochimique le stent avec le modèle désiré de toiles métalliques et à implanter le stent chez le patient. Le procédé consiste à utiliser une cathode (150) avec un modèle désiré de toiles métalliques et une ébauche tubulaire (250), à partir desquels on forme le stent. Un électrolyte est envoyé entre la cathode et l'ébauche, puis la cathode et l'ébauche sont simultanément tournées pendant le procédé de formage électrochimique.
